MANUFACTURE OF INSULATED WIRE.

SPECIFICATION forming part of Letters Patent No. 703,197, dated June 24, 1902. Application led February 23, 1901, Renewed November 2l, 1901. Serial No. 83,173. (No model.)

To @ZZ whom, it may concern:

Be itknown that I,JOHN A. HEANY,a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented cer tain new and useful Improvements in the Manufacture of Insulated W`ire, of which the following is a specification.

My invention has relation to an apparatus for the manufacture of insulated wire, and in such connection it relates to the construction and arrangement of such an apparatus.

The principal object of my invention is to provide an apparatus adapted to cover or coat a metallic wireV or electric conductor with a non-combustible material, such as asbestos in flaky form, and' to solidly secure said material to the wire under pressure or otherwise, so that the covering or coating will not readily dissipate, crack, or peel o under heat, under torsion of the wire, or otherwise.

The nature and scope of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, in which Y Figure l is a front elevational View, partly in vertical section, of an apparatus embodying main features of my invention. Fig. 2 is a top or plan View of the apparatus. Fig. 3 is a detail View, in horizontal section, illustrating the fan or blower and the means whereby motion is conveyed to the same. Fig. it is an enlarged cross-sectional View of the reel upon which the coated wire is adapted to be wound and of one of the pulleys around which the wire is passed prior to its delivery to the reel. Fig. 5 is a vertical sectional view on the line 5 5 of Fig. a., Fig.'6 is a detail View, enlarged, of the pressure-rollers for compressing the coating or covering of the wire; and Fig. 7 is a detail view in perspective of the track upon which the fan-operating wheel rotates.

Referring to the drawings, a represents the bed of the machine, supported above the door upon the legs or supports a. Below the plate a is located a standard b, within which rotates a shaft carrying a reel b, upon which the uncoated wire b2 is coiled and from which the wire is to be unwound. From the reel b the wire passes over a wheel b3 and into a tank b, containing an adhesive mixture b5. Within the tank b4 is located a guide-wheel t, under which the wire b2 passes, so as to insure its passage through lthe bath or mixture b5.

Projecting from the bed a and above the tank b4 is a bracket or bearing d, in which is adapted to turn a tubular or hollow shaft d. This shaft d also traverses the bed a and turns within a suitable block or bearing d in said bed. Upon the hollow shaft d is keyed or otherwise secured a grooved pulley d3, connected by a belt or cord d4 with the main driving-pulley d5 of the machine. To the upper end of the hollow shaft d' is secured the base e of a drum-like receptacle e', which as the shaft d and base e rotate is adapted to revolve around the hollow of the shaft d as an axis. The drum e is divided into two main compartments by an inclined partition e2, which supports centrally of the drum e' a tube c3 to permit of the passage of the wire b2 afterithasbeencoatedthroughthedrum. The uppercompartmentetis adaptedtocontainthe non-combustible material,usually asbestos,in iiaky form, auditserves as a hopper to feed the material to a third and lesser compartment at one side of the drum e. At the base of the outlet from the compartment e4 into the lesser compartment is arranged a picking or breaking-up wheel f, by means of which the flakes of material arel torn apart or shredded. Below the picking-wheel f is located a screw conveyer g, which conducts the shredded material from the picking-wheelfto the outlet the picker-wheel f, the shaft g of the screw conveyer g, and the shaft t" of the fan or blower i are all rapidly rotated by the following preferred arrangements:

Concentric with and inclosing the base e of the.drumlike receptacle e is a circular track k, supported by and above the bed a of the machine by suitable brackets 7c'. Upon this track 7c is adapted to travel as the drum e revolves a friction-wheel t2, secured to the shaft c" of the fan or blower i. As the drum rotates the friction-wheel i2 rapidly revolves and rotates the shaft 'i' and fan or blower 'L'. On the shaft t' is also secured two pulleys m a-nd lrn', one of which, m, drives, through a belt m2, a pulley g2 on the shaft g/ of the conveyer g to revolve said conveyer,and the other, m', drives, through a beltm3, a pulley]c2 on the shaft f' of the picker-wheel f to cause said wheelf to revolve. The track k is adjustably connected to the brackets 7c by the following preferred means: Depending from the track 7c is a series of ears or lugs k2, .each slotted, as at 7c3, to receive a bolt 7a4. The bolts 7a4 pass through the brackets 71: and through the slots 7c3 of the ears or lugs k2, andby means of the nuts h5 the ears or lugs 7a2 may be tightly clamped to said brackets 7c. By loosening` the bolts 7J" the track 7c may be elevated from or depressed toward the bed @,so as to permit of the use of one of a number of frictionwheels i2 of varying diameters upon the shaft i" of the fan or blower r, and hence the speed of said shaft and blower may be increased or decreased, as required, by the elevation or depression of the track 7c and the substitution of a wheel 2 of required diameter. y

Below the partition e2 is the second main compartment e5, arranged to receive the refdrum e.

So far as explained the operation of the apparatus is as follows: After the wire b2 has been coated with the adhesive mixture it is drawn upward through the shaft d and through the tubular extension 7a' of the funnel 72. As the drum e' revolves the fibrous and flaky material is blown through the funnel h by the fan or -blower 'i upon the entire periphery of the wire and thoroughly covers the same, the non-combustible material adhering to the adhesive coating and forminga furry loose covering or layer b3. Thus covered the Wire b3 is drawn upward through the partition @aand the tubular extension e3. The wire is now ready for the compressing operation.

Supported upon the bed a and projecting Aupward therefrom is an inverted-U-shaped standard a2, forming a bearing, as at as, for a vertically-arranged and hollow revoluble shaft CL4. This shaft afprojects downward in set consisting of two rollers, the grooved peripheries of'which approach each other to form an opening, as illustrated in Fig. 6, through which the coated wire b3 passes. Set or adj usting screws n and o', respectively, regulate the distance separating the rollers n or o of each set, and the set ois arranged, preferably, in a plane at right angles to the plane of the other set n, although the grooves of the rollers of both sets are arranged in a vertical plane. Upon the shaft a4 is secured a driv ing-pulley a5, connected bya belt a with a pulley al, which is driven by a belt as, connecting the pulley a7 with the main drivingpulley d5, When, therefore, the machine is in operation, the wire b3 passes upward between the two sets of rollers n and o, which turn with their shaft a4 and compact or compress the furry covering of the wire with a spiral action down upon the wire. The wire b3 'next passes over a guide-rollerp and then is wound around a tension and feed roller p, located upon the shaft a9, to which the pulley o7 is secured. The wire next passes, preferably, around two guide-rollers p2 and is fed to and wound upon a revoluble spool p3.

Referring now to Figs. 2, 4, and 5, the spool p3 is arranged loosely upon the shaft of and is connected by a bent arm or pin p4 to a split sleeve or collar p5, adapted to frictionally contact with a grooved collar p5, secured to and traveling with said shaft a9. The split sleeve p5 is bound frictionally to the grooved collarp6 by means of the bolts p7 to such an extent as to permit the spool 293 to travel with the shaft a only when the wire b3 is to be wound up at a certain rate of speed. Inasmuch as each succeeding layer or coil of wire b3 on the spool p3 is longer than the preceding coil, and inasmuch as the feeding of the wire to the spool is regulated by the tension and feed rollerp, which travels at the uniform speed of the shaft a, the speed of the spoolp3 must be retarded more and more as each succeeding coil is laid on the spool. The connection of the spool p3 to the friction collar` or sleeve p5`by` means of the bent arm or pin p4 permits the spool p3 to be revolved by the shaft a9 at a gradually-decreasing speed, the differences in speed being taken up by the slipping of the split sleeve p5 .on the collar p6. c
